SPRING-TIRE.

To all whom it may concern:

Be. it known ythat I, Tnonas .lanas Mc- CARTHY, a citizen of the lnited States ol" Ainerica, and a resident of the city ot Los Angeles, in the county ol' Los Angeles and State ol California, have invented a new and useful Spring-Tire, of which the following is a siecitication, reference being had therein to t ie accompanying drawings.

This invention aims to proved wheel tire, which wil not onlv be an adequate substitute for, but really will prove to be an article in every respect superior to the pneumatic rubber tire, such as is used on the automobile or horseless carriage.

Patrons of the automobile are well aware of the fact that the pneumatic rubber tires are costly and short-lived at best. rl`hey are liable to be puiictured or cut up and to burst at the most inopportuni` moment, and for y that reason, extras have to be carried on g ienever occasion demands. lt is estimated, by persons tainihar with tiade conditions, that the. replacing and renovating of pneumatic tii'cs on an antoiiiobile amount to hilly twenty per cent. ot' the cost thereof in a single vear. The need is therefore felt of a tire, other than thi` pneumatic, that will bc durable as well as resilient, prooi'. against punctures and cuts, and capable. .ol' withstanding rough usage to a reasonable extent. lf these features be realized, with simplicity ol' construction and inexpciisiveness ot inanufacture, then a practical, ideal tire is obtained. Such a tire, it is believed, the pi'esent invention atl'cz'en.

Referring to the dra\\'ings,-Figure l is a sectional side elevation ol' a wheel having a tiremade in accordance with the invention. Fig. 2 is a vertical cross section oi" the saine. Figs. 2%, and 4 are details, showing lraginentary parts of the tire on an enlarged scale.

ln these various tigures, let the numeral t i'cpresent the hubot thc wheel; 2, its spokes; and 3, the l'elly. No novelty is claimed in these pai'ts (l, 2, 3,) which niay be ot' any approved construction.

'lhe improved tire com irises two concenti'ic circular bands of metal 4 and ."i, an anni:- lar series ot'v radial springs (i therebetween, pairs of lateral springs T and S similarlyinclosed but diagonallyr arranged and running in opposite directions between the said radially-disposed springs, and a cushion tread t). ly preference, the said bands and Specification of Letters Patent.

Application tiled March 27,

provide an iniaourney in order to replace the ruined ones w Patented Jan. 28, 1908.

t intervening springs are made of steel, and the tread of solid rubber.

Within the inner band 4 are provided two narrow tlanges 1t) and 11, between which the telly it is tted, the band thus forming a shoe therefor, and being secured thereto by any `ysuitable fastening. Out-wardly the band 4 is also formed with another pair ot wider i [langes 12 ano 13, between winch are seated the radial springs 6. These springs are conxeniently made of spiral forni antl )laced i endwise upon fittings i4, consisting o small t plates bent to the curvature of the, ieriphery i of the band 4 and'securely bolted thereto. l the inner end ot' each spring being threaded l or passed. through eves or staples l5 and 16 on opposite sides oi its respective plate or titting andhooked to one of theni. Upon the outer end of each spring ti, is placed another titting or plate 1T, having likewise tippositely-located eyes or staples 18 and 19, 5 through which the said outer end is passed or i threaded and to one of which it is hooked. i

'lhis second plate or littinir is bent to the curvature of the outer band o, as shown.

Besides the aforementioned eyes or staples l5, lt, 1S, 19, t-lie two plates or tittings 14 and 1T are further provided each with four lugs 2t), 2l, 'N one at each coiiiei, the saine being slotted. as at .24, and adapted to 'lhe hist named springs (7 and S) have a hook .5 at each end, which is so formed that it can be readily dropped into any one of the slots 4 and will beat' equally on opposite sides of its respective lug, thereby preventing displacement ol' any ot' the springs in either i direction. 'lhe springs 7 and b.' are placed in pairs one on each side ot' the tire, within the saine, and are crossed as illustrated, the said springs being hooked obliquely and oppositely to and between the several paii's'of tittiiigs 14, and t'i'. Thus. for instance (looking at ltig. l ol' the drawings), the spring T on the let't ol' the uppermost radial spring ti will be hooked by its upper end to the titting t7 and 5 by its lower end to the littiiig t4 farther on I the lett, whereas the spring S on the saine side will be secured at its lowei end to the titting` l-t and at its upper end to the titting 1T, and so on t'or the other lateral springs I vthroughout the tire.

'llu` outer metallic band 5 is applied in two or more sections, which are riveted or bolted to the outer tttings or plates t7 and are i otherwise suitably joined togethcri': This receive either end of one ot' the springs 7 or S.

formed on the-outer periphery of the band which afford a convenient retaining means.

,for the cushioning band of rubber 9, although the latter may be shrunk on, if preferred. And the latter-named band 9 may be ribbed lengthwise and crosswise, or pitted Vor1r0ugh surfaced, to prevent sliding, and

it may also be .of other material than rubiber, for example, leather or any suitable substitute. y

` It will be readily seen that when a set of tires of the improved type above described are laced on the wheels of a vehicle, the weig t ofthe vehicle and load thereon will cause compression of the radial s rings 6 that are at the bottom of each wheel), and correspnding rdistention of those at the top, whilethe inner bandv or rim 4 will move up and down within the outer one, and the lateral springs 7 and 8 will have a tendency tohold the radialr springs at the sides of the .30' wheel in pro er position, therebyl equally distributingl t e strain throughout the circumference of the wheel.

'A Having thus described my invention, what li I claim, and desire to secure by Letters Patent of the United States, is:

1. A wheel tire com rising concentric bands, one embracing an radially movablev and said bands and provided with lugs at I each corner, andtwo sets of diagonally-disposed springs arranged side by side between each two of said radlal s rings and connected at .their opposite ends wlth said lugs from'the upper corner of one fitting to the lower corner 'of the other iitting.

2. A Wheel tire com rising two circular bands anged one over t e other, an annular series of s iral springs radially seated within said bands, fittings on the ends of said springs and having lugsl at each corner, means for anchoring the springsvlto the fittings, pairs of diagonally-disposed springs arranged side. by side-'between said radial s rings and running obliquely in opposite irections, and means for securin said diagonal s rings to said fittings and or engagin said ugs on o posite si es thereof.
